Hello,

I am using okl4_2.1. I want to build and simulate for machine KZM. I run the
command 
 ./tools/build.py machine=kzm_arm11 project=iguana  verbose_str=True
simulate
All the images .elf .sim and .boot are built but there is some error in
simulation "Can't open tools/unittest/kzm-boot.sh". 
This is a problem caused by the okl4 build scripts.
Go to tools/simulators.py and change entry for kzm_sim.
The okl4 guys did not make the tools/unittest/ folders publicly available. 

If I understand correctly from wiki, Qemu 0.9.1 can be used to simulate
wiki. I have downloaded and built Qemu with the configuration option :
./configure --target-list=arm-softmmu --disable-sdl --static
--disable-gfx-check
make
However qemu-system-arm -M ? does not give kzm as an option. (I am using gcc
4.2.4).

A possible explanation is that you have more than one qemu set up on your linux box. Ubuntu comes with it's own qemu which does not support kzm (but has a qemu-system-arm).

You need to take into account that make (if it completes without errors) will generate in arm-softmmu/ the qemu-system-arm of your choice. BUT it is not available throughout the linux box yet. Only after you symlink it in /usr/local/bin or add it to your bashrc. $PATH.

Here is how it looks on my end after I build this qemu and create a symlink to arm-softmmu/qemu-system-arm in /usr/local/bin:
gabi at gabi-linux:/proj/okl4_2.1$ qemu-system-arm-kzm -M ?

Please help.

Also when I try to build l4 with linux 
 ./tools/build.py machine=kzm_arm11 project=iguana  verbose_str=True
wombat=yes simulate
it says
projects/iguana/SConstruct:634 Error: OKLINUX_DIR: linux: does not exist

Could you please let me know where I am going wrong?

Thanks
Aparna
